Method for manufacturing non-transparent adhesive and the product thereof

Abstract

A method for preparing an opaque adhesive comprising adding a titanium dioxide nanoparticle or a quantum dot to a matrix of a binder. The titanium dioxide nanoparticle is spherical or rod-shaped. The process exhibits superior thermal and chemical stability. The non-transparent adhesive incorporates TiO2 nanoparticles or a quantum dots into an adhesive matrix to form a chromatic composite adhesive, wherein the TiO2 nanoparticle is rod-shape or sphere-shape.

What is claimed is: 
     
         1 . A method of preparing an opaque hybrid composite adhesive comprising adding titanium dioxide nanoparticles or quantum dot nanoparticles to a binder matrix. 
     
     
         2 . The method of  claim 1 , wherein the titanium dioxide nanoparticle or quantum dot nanoparticle has a weight percentage of 0.001 to 5 wt. %. 
     
     
         3 . The method of  claim 1 , wherein the titanium dioxide nanoparticles are rod-shaped or spherical. 
     
     
         4 . The method of  claim 1 , wherein the quantum dot is a cadmium selenide quantum dot. 
     
     
         5 . The method of  claim 1 , wherein the titanium dioxide nanoparticles are prepared in a sol gel. 
     
     
         6 . The method of  claim 1 , wherein a surface of the titanium dioxide nanoparticle has a modification of a derivative pigment. 
     
     
         7 . An opaque hybrid composite adhesive comprising a binder matrix and titanium dioxide nanoparticles or quantum dot nanoparticles added to the binder matrix.
